Relationship between Gestational Age and Placenta Thickness during Third Trimester

Abstract

The purpose of this study to estimate the correlation between placenta thickness (PT) and fetal age(FA) in normal pregnant women. The study was done on 50 normal pregnant in third trimester. The data used in the study collected in Saudi Maternity Hospital in Omdurman during 2016. The used ultrasound machine with a frequency 3.5MHz convex probe.The results of the study showed that there is a positive correlation between placenta thickness and gestational age (GA) .It was found that the placental thickness gradually increased with the increase of gestational age. where the placental thickness in millimeters coincide almost exactly the gestational age in weeks special from early weeks of third trimester to the 35th week of gestation .the study showed the maximum placental thickness of 50 millimeters was recorded at 32 weeks gestation. It is recommended further studies to estimate the fetal age by using placental thickness for different nationalities or with abnormal pregnancies.
